BOX-STRAP.

SPECIFICATION forming part of Letters Patent No. 403,178, dated. May 14,1889.

Application filed March 5, 1888. Renewed October 13, 1888. Serial No.288,048. (No model.)

To all whom it may concern: 1

Be it known that I, SPENCER O. CARY, of Baldwin, county of Queens, Stateof New York,a citizen of the United States, have in- 5 vented anImproved Box-Strap, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My invention relates to a metal box-strap;

and it consists in a box-strap composed of a metal band having a seriesof successive bosses at each side edge and extending longitudinallythereof, substantially as hereinafter particularly set forth, and forthe purposes hereinafter specified.

Figure 1 is a plan of a box-strap containing my invention. Fig. 2 is avertical longitudinal section of the same on line m ac, Fig. 1. Fig. 3shows my improved box-strap bent or turned flatwise over the corner of abox or packing-case. Fig. 4 is a plan showing the lapped ends of twolengths or sections of my improved box-strap and the joint which Iemploy to unite the same to constitute a contin- 2 5 uous band; and Fig.5 is a vertical cross-section on the line y y, Fig. 4.

A represents a metal band of indefinite length.

At B B are shown series of successive bosses 0 formed upon one and thesame face of the band A and projecting above said face at each sideedge, respectively, of the band,and extending throughout the lengththereof. These bosses may be circular in outline, as shown, or may 3 5be given any other outline desired. Theyare arranged in series, asstated, along each of the respective side edges of the band, and betweenthe adjacent members of each series is a web of the metal of the band,as shown at b b in the respective series. This intervening web or faceof the hand between the members of each series may be greater or less inextent, as may be desired, without material variation from the essentialfeature of my invention.

In carrying out my invention I find it pref= erable to have the bossesin each series set or formed in near proximity to each other, as shownin the drawings, with the space or web of metal between them of somewhatless extent than the diameter or length of the bosses themselves, asshown. I also find it prefer:- alole to have the bosses of uniform shapeor outline and size or extent, and to have them arranged equidistantfrom each other throughout the series, as shown, and with eachindividual boss in the series at one edge of the band located oppositeto an individual boss in the series at the other edge, as shown. whenthus constructed, the ends of two lengths or sections of the strap maybe overlapped, and the crowns or projecting surfaces of the series ofbosses on the under section will fit into the recesses constituted bythe bosses in the upper section, on the under face thereof, therebyenabling the lapped ends to constitute an even fiatwise joint upon eachother. When the ends are thus overlapped, I am enabled to form apermanent joint between the sections of band by punching a hole, 0,through the central portion or web of one of the sections of band at ornear the end thereof, and cutting through the web portion of the otherband in radial slits, so as to form therein the lugs or ears 0', adaptedto be turned around and over the rim of the hole 0 and down upon theexposed face of the section in which said hole is formed, as stated. Inplace of doing this the equivalent thereof may be donenamely, punchingcorresponding holes in the lapped section ends and securing the endstogether by an eyelet passed through said holes and clinched down uponthe webs of the bands.

The advantages of a joint between two sections or lengths of my improvedband, formed as described, are that the overlapped bosses at the strapedges serve to assist in withstandin g any longitudinal and lateralstrain or pull upon the joint or union, while the hole 0, when the jointis completed, as specified, constitutes an aperture in the strap throughwhich a nail o may be driven when the strap is seated upon and fastenedto a box or packing-case, so that the joint of the section ends will beheld rigidly and be prevented from separation.

It is evident that a box-strap constructed 5 as I have described may bebent or turned over and around the corner of a packing-box, as shown inFig. 3, with the bend or turn formed in the Web or portion of the strapbetween the bosses of each series, as at b b, and too that the liabilityof the metal band to crack or fracture across the crown of the bosses,which is exceedingly liable to occur when there are continuouscorrugations along both edges of the strap, is wholly obviated. Theattainment of this result is most desirable, as the fracture of thecontinuous longitudinal corrugations in a box-strap produces sharpragged edges, projecting from the strap at its angular turns on thepacking-case, which are liable to damage objects with which they maycome in contact and to injure the hands of the handlers, as well ascausing a weakening of the strap at the places where the greatestholding strength is demanded.

It is also evident that the bands corrugated in the manner set forth andconstituting the material of my improved box-strap may, when united atthe ends of their sections, be reeled up or coiled helically, thewebbing of hand between the bosses of each series, as set forth,permitting this coiling to be effected, and that the material thuscoiled may be unreeled as desired, to be employed in bindingpackingcases, and may be cut or severed at the points or places wherethe required length of each box-strap terminates without regard to thelength of the sections of band constituting the reeled strappingmaterial, and thus all waste of material may be obviated. Metalbox-straps composed of plane or corrugated bands, as hitherto formed,have been made in different lengths or sizes-the longer for large casesand the shorter for small ones; but as packingcases vary in size thestraps are seldom accurately adapted to the case upon which they arebound, and hence, when too long, a waste of the unnecessary length ofband is occasioned. My strap having successive bosses,

as specified, is peculiarly adapted to be united in lengths endwise, andto be, by being reeled,

put in a shape convenient for handling and to be withdrawn from the reelor coil in the exact lengths required, thus avoiding all waste orunnecessary consumption of material.

The series of successive bosses described constitute a guard for theheads of the fastening-nails by which the box-strap is secured to thepacking-case, the said nails being driven through the body of the strapbetween the rows of edge bosses, the heads of the nails being thusprevented from abrading objects with which the strapped case may come incontact.

hat I claim as my invention, and desire to secure by Letters Patent,is-- 1. A box-strap composed of a metal band having a series ofsuccessive bosses at each side edge and extending longitudinallythereof, substantially as and for the purpose set forth.

2. A box-strap composed of a metal band having bosses of uniform shapeand size and equidistant from each other in series along the side edgesof the band, each individual boss in the series at one edge beingrespectively opposite to an individual boss in the series at the otheredge, substantially and for the purpose set forth.

3. A box-strap of indefinite length composed of metal bands havingsimilar bosses succe, sively in series throughout their length, withtheir ends overlapped fiatwise, with the said similar bosses fitted toeach other in the respective bands and provided at or near their saidlapped ends with corresponding transverse apertures, with the rimsthereof clamped together, substantially as and for the purpose setforth.
